Adding in warning if the input vtkPointData structures is different.

These filters use vtkDataSetAttributes to interpolate input
point data to the output polydata so we need to make sure
that the point data structures match on all processes and
data sets. If they don't, the filters now return an error
and fail.

Reduce memory usage for TestCheckerboard

This reduces the memory usage for TestCheckerboard by reducing the
Z extents of the images from 99 to 10. This reduces the memory usage
of the test from ~170MB to ~37MB.

This should fix the test on AIX where it was running out of resources.

Reduce TestProjectedHexahedra window size to 500x500.

The previous window size of 800x800 seemed needlessly large, and causes
test failures on screens with a height of 800 or less (e.g. some laptops).
